The player doesn't show up until a few seconds into the clip, the only happens in the render and camera path, it doesn't happen if I just play the replay normally. It's not as delayed in the video, as it is in the camera path, in which the player doesn't appear for a whole 8 seconds... (Seen here: https://www.youtube.com/watch?v=qv3qjINYqU8)
Is this issue any different on 2.1.4 (both during path playback and during render)?
I remember putting various workarounds in place to combat this issue as far as possible (it's unfortunately fairly fundamental to how the RM works). However, it's been a while, I'm not using the mod myself and people have a tendency to never report such issues, so it might have stopped working at some point (possibly even before 2.1.4).
I'm unable to reproduce this for rendering.
While I am able to reproduce it for path playback, I am unable to come up with any reasonably simple fix (only fairly complex ones which can very easily break other stuff especially across different MC versions), so I'm going to leave this as is for now.
Until I (or someone else) revisits this issue, please just add an extra second of (normal speed) playback at the start of your path to work around the issue.
